It's a half circle plus a triangle.
The diameter of the circle is 23.1 ft so the radius is 11.55
Area of a circle is πr²
Area of a triangle is (1/2)bh
Area shape = (1/2)πr² (1/2)bh
A = (1/2)π(11.55)² + (1/2)(23.1)(29.4)
A = 549.1181
75 in^2, because 5 times 5 (the split up hexagons make parallelograms and there is 3 of them, and parallelogram area is base times height.)
Answer:
The second answer choice; (0,1) (3,2) (6,3) is your answer.
Step-by-step explanation:
I don't know how to explain this but here's a picture of the line; y=1/3x+1
I hope this helps! :)
Answer:
We are 90% sure that the true proportion of Americans who approve the ppresident's policies is in the interval from 42% to 46%.
Step-by-step explanation:
A confidence interval of a proportion p% at the x% level with m% margin of error means that:
We are x% sure that the true mean of the population is in the interval from (p-x)% to (p+x)%.
In this problem, we have that
90% confidence level
44% with a margin of error of 2%
So:
We are 90% sure that the true proportion of Americans who approve the ppresident's policies is in the interval from 42% to 46%.
11^2=121
12^2=144
You can write either 11 or 12.
